Google Earth Engine ——美国LANDIFRE火灾LANDFIRE FRG (Fire Regime Groups) v1.2.0数据集

LANDFIRE (LF), Landscape Fire and Resource Management Planning Tools, is a shared program between the wildland fire management programs of the U.S. Department of Agriculture's Forest Service, U.S. Department of the Interior's Geological Survey, and The Nature Conservancy.

Landfire (LF) Historical fire regimes, intervals, and vegetation conditions are mapped using the Vegetation Dynamics Development Tool (VDDT). These data support fire and landscape management planning goals in the National Cohesive Wildland Fire Management Strategy, the Federal Wildland Fire Management Policy, and the Healthy Forests Restoration Act.

Fire Regime Groups (FRG) are created by linking the Biophysical Settings (BPS) Group attribute in the BpS layer with the Refresh Model Tracker (RMT) data and assigning the FRG attribute. This geospatial product should display a reasonable approximation of FRG, as documented in the RMT. (LF 1.0.0 CONUS only used the vegetation and disturbance dynamics model LANDSUM.) FRG can be used in landscape assessments.

The LANDIFRE Fire datasets include:

• Fire Regime Groups (FRG) is intended to characterize presumed historical fire regimes within landscapes based on interactions between vegetation dynamics, fire spread, fire effects, and spatial context
• Mean Fire Return Interval (MFRI) quantifies the average period between fires under the presumed historical fire regime

LANDFIRE（LF），景观火灾和资源管理规划工具，是美国农业部林务局、美国内政部地质调查局和大自然保护协会的野地火灾管理项目之间的一个共享项目。

土地火灾（LF）历史上的火灾制度、间隔和植被状况是用植被动态发展工具（VDDT）绘制的。这些数据支持《国家统一野地火灾管理战略》、《联邦野地火灾管理政策》和《健康森林恢复法》中的火灾和景观管理规划目标。

火灾制度组（FRG）是通过将BpS层中的生物物理设置（BPS）组属性与刷新模型跟踪器（RMT）数据联系起来，并分配FRG属性而创建的。该地理空间产品应显示FRG的合理近似值，如RMT中记载的那样。(LF 1.0.0 CONUS只使用植被和干扰动力学模型LANDSUM)。FRG可以在景观评估中使用。

LANDIFRE火灾数据集包括。

火灾制度组（FRG）旨在根据植被动态、火灾蔓延、火灾影响和空间背景之间的相互作用，描述景观内假定的历史火灾制度的特点。

平均火灾重现间隔（MFRI）量化了假定的历史火灾制度下火灾的平均间隔时间。
